Did you have fun reading the USB audio spec stu? What a document that one is! I've just had the misfortune of reading it as I've just added a "PC interface" to our doppler radar (aka speed detector) interface and decided the nicest way of doing it was to pass the "doppler audio" straight into the "PC".
All I can say is that I'm glad that they include sample descriptors in the usb audio document otherwise I think I'd still be trying to decipher what exactly is needed in them!
We glossed over some of the general USB specs but since the actual code is executed in silicon I guess the specifics of the audio protocol were of little concern. You make it sound like a great read though. I might just check it out!
By the way, the USB org has decided that mini AB connectors such as we have used in our prototypes are illegal now (they decided this after development started). So now if we ever want to certify our device we must go to a micro AB connector. Yay!
